(3) in wild-type individuals, the operon is transcribed in the absence of compound B but not in the presence of compound B. (4) In reg mutants, the operon is constitutively transcribed. Is this operon inducible or repressible? Why? O It is inducible because wild-type transcription does not occur in the presence of compound B O It is inducible because the operator in reg mutants can still bind to compound B O It cannot be determined because the number of structural genes is unknown. O It is repressible because reg transcription only occurs in the presence of compound B O It is repressible because wild-type transcription is repressed in the presence of compound B Previous Give Up & view salution chodkAnswer Next Exi Type here to search acob Assignment Information Available From: 6/7/2017 2:00 PM Due Date: 6/13/2017 09:45 AM Points Possible 5 Grade Category: Homework Description Policies: You can check your answers.

ANSWER) The answer will be, it is a repressible operon because in represssible operon it need tobe repressed by sothinf and in this case the compond B is ating like repressor of te operon as iin the question it is known that in the presence of the commpound B which was earlier formed by compounnd Q reperssing the operon may be the repressor which is inactive normally this compound B is activating the repressor and that repressor will bind to the operator and the RNA ploymerase willnot move further this stopping the operon.
